This invention relates to an improved form of nut, and has for itsobject the association with an ordinary centrally bored and threaded nutof a metal Wrapping, which, as hereinafter described, is renderedstructurally integral with the nut, and Yet a portion of which Wrappingis adapted `or interlocking engagement with a metallic sheet or similarelement placed in association With one end of the nut. The particularuse which I have in mind for such a construction, though of course I donot limit myself thereto, is the p0- sitioning of the nut in firmstructural relation to an automobile door or body so that the threadingof the nut may be used as the base or .anchorage from which to supportsome other structural part of the vehicle body, as a bolt, post, or thelike.

In the drawings:

Figure l is a view of a fragment of a metallic sheet to which the nutstructure herein disclosed has been applied, the position of all of thenut structure except the perforatin locking projections being indicatedin otted lines only, because located on the far side of the sheet ofmetal.

Figure 2 is a sectional elevhtional view taken along the line 2-l-2 ofFigure 1 and looking in the direction of the arrows there shown.

Figurev 3 is a perspective of the assembled nut and its wrapping.

v Figure 4 is a view of the underface of the nut.

Figure 5 is a plan View on a smaller scale of the metallic Wrapping forthe nut body as such, as spread out`when first eut from a blank andbefore being bent about lthe nut body.

Figure 6 is a view of a slight modification as regards the correlationof the nut structure and the sheet metal panel, in that a D-shaped holeinstead of a squared hole is formed in the nuts metal Wrappmg.

A indicates a metallic sheet, such as a bodyv or door panel of a motorvehicle, with which it is "desired to structurally correlate the nut B,which may be of any desired size or shape,

- either squared or hexagonal, and whose function when properlyassociated with the metallie sheet A is to serve as an anchorage or base'for some other structural part whose irm connection with the sheetmetal panel A is desired. t

As Drought out in Figure 3 particularly, I preferably lassociate aboutthe nut body B a sheet metal stamping or Wrapping C, which, except forthe centrally apertured or cutaway porton, hereinafter to be described,covers one end surface of the nut body, as D,

'and in addition has marginal edge portions,

as E, which are of corresponding shape and size to the sides of the nutbody B and are bent thereover into substantial. alignment with theseveral surfaces thereof. It will of course be possible to extend eachside-engaging portions E for further bending into surface engagementwith the edge portions of the underface of the nut, but I have found itentirely satisfactory and sutcient to merely provide along the centralouter edge of each side piece E, or even two or more of these though notall four, a lip or projection F, which is bent into position ofsubstantial parallelism with the underface of the nut body B. ThisWrapping or bending about the nut body of the partsD, E, and F resultsin firmly correlating the two so that, with the metallic wrappingsuitably associated with a metallic sheet, the threaded body of the nutmay then be employed as an anchorage or base for the suspension orattachment of an external structural part.

To 'effect this, I aperture the central portion of the wrapping, whichwould other- Wise-close the top end of the nuts threaded bore,preferably, and as herein illustrated, by cutting four Wedge-shaped orpartially vtriangular lips or flaring branches G, each of which is Ybentto a position of substantial perpendieularity to the plane of the topsurfaces of the Wrapping. Each of these is adapted to perforate or to bepassed through the metallic panel A, and thereafter to have its extremetip portions, as H, bent over into clinching position against theopposite I face of the metallic panel A from that against` the opposingdirections in which the overbending or clinching of the tips of theselips takes place results in the effecting of a very firm anchorage ofthe wrapping and its enclosed nut body.

In Figure 6 I have illustrated the adaptability of my idea to a nutsheathing wherein the aperture, whose upstanding edge ortions areadapted to be passed through the metal. panel or sheet, is shown as ofwhat might be called D-shape. In this form, that side of the aperturerepresented by the straight edge of the D-shaped hole may or lnay nothave an upslanding lip or projection, While the remaining sides of theaperture, being in a continuous though not necessarily truly circularlille, may be made con- Atinuous as to its upwardly projecting lipportion or may be separated into two or more parts, as indicated at J.The, wrapping of the sheathing about the body of the nut is the same asthat already described.

While it will be apparent that the illustrated embodiments of myinvention herein disclosed are well calculated to adequately fulfill theobjects and advantages primarily stated, it is to be understood that theinvention is susceptible to variation, modification and change withinthe spirit and scope of the subjoined claims. f

What I claim is:

.1. Means for structurally positioning a centrally bored and threadednut body upon a laminary surface, comprising a unitary f sheet metalwrapping applied about all of the lateral faces 'and about selectedmarginal portions ofy the end faces of the nut, the initially centralportion of the sheathing adjacent one end of the nut being aperturedwith the edges of the sheathing surrounding the aperture extendingoutwardly for passage through, and locking engagement with, the laminaryelement with which the association of the nut is desired.

meager nut from turning, and said portion protruding through saidaperture being deformed 1n ependently of the nut to serve as the solemeans for rigidly locking the casing and hence the nut unit to the sheetmetal article.

4. Fastening structure of the type wherein a nut is attached to a sheetof metal for the reception of a bolt, comprising a nut unit including astandard nut member at least partially enclosed on the sides, bottom andtop by a sheet metal casing, said sheet metal article being provided witan aperture and said sheet metal casing being provided With an extensionprotruding through said aperture, said casing being so shaped and saidextension being turned over to permanently clinch the sheet metalarticle between two lsurfaces of said sheet metal casing whereby saidnut unit is permanently attached to the sheet metal articleindependently of the nut member.

5. As a new article of manufacture, a nut unit of the type adapted to bepermanently clinched in an aperture in a sheet metal article, comprisinga substantially square standard nut element for receiving' a bolt, andan exterior member having fixed walls enclosing a portion of the top andbottom walls and side walls of the nut, said exterior member having aportion non-rotatably cooperating with said aperture in said sheet metalarticle and being permanently distorted to serve as the sole `means forclinching the nut unit in position.

In testimony whereof I sign this specification. f l

2. In combination with a nut body, a sheet metal wrapping engaging overthe sides and marginal parts of the end portions of the nut, the centerportion of the wrapping being cut and upwardly bent at a plurality 01'?`points surrounding the centrally bored portion of the adjacent end ofthe nut, lforming tongues for passage through a metallic sheet whereonthat end of the nut is positioned and with which each tongue is adaptedto be bent into interlocking engagement.

3. Fastening structure of the class wherein a nut it attached to a sheetof metal for reception of a bolt, comprising a threaded nut memberenclosed within-a sheet metal casing, a portion of said casing extendingat right angles to the plane of the nut, said sheet of metal beingprovided with an aperture for receiving the extending portion of thecasing, said sheet metal casing and nut being complementally shaped toprevent the
